Application of Error-Correcting Codes (ECCs) for efficient message transmission in Vehicular Ad Hoc Networks (VANETs)

Abstract

In this paper, we presented an adaptive application of forward error code (FEC) for efficient message transmission in vehicular ad hoc networks (VANETs). Our solution is a combination of automatic retransmission request (ARQ) with FEC at the MAC layer. The proposed scheme used the existing channel condition, an estimate of the maximum number of transmissions before the message deadline elapses and message type as an index in code lookup ensemble (CLE) to get an optimum code (optCode) for the current transmission. Furthermore, the system also set the transmission timeout delay RTTRTT, encode the message with the optCode and transmit. However, if the transmission timeout delay elapses before receiving an ACK/NAK, the scheme will return to the initial stage for feasible retransmission of the message. We evaluated the scheme and compared it with the static FEC for reliable and timely safety message transmission; our system outperformed the static FEC in all cases that we have considered.
